MOP WRINGER Filed Dec. 22. 1928 Patented Mar. 17, 1931 PATENT OFFICE OLIVER 1. GREENSTREET, OF OWENSVILLE, MISSOURI MOP WRINGER Application filed December 22, 1928. Serial No. 327,965.

This invention relates to mop wringers of that character wherein two rollers are provided between which the mop is disposed when the mop is wrung out, the rollers being 6 forced together for the purpose of squeezing the water out of the mop.

The general object of the present invention is to provide a construction of this character wherein the mop rollers are disposed in a horizontal planeso that the mop may be readily inserted into the water bucket or re moved therefrom and removed therefrom While being wrung out.

A further object is to provide a construction of this character wherein one of the rollers is fined upon the supporting frame and the other roller is so supported that a spung holds it apart fromthe first-named roller and a pedal is provided for forcing it toward the first-named roller, the spring under these circumstances acting to yieldingly urge the rollers toward each other and thus secure a yielding pressure against the mop as the mop is being withdrawn from the wringer.

'A further object is to provide a device of this character which is adapted to receive a water bucket and in which the wringing mechanism is not made as part of the water bucket.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a top plan View partly in section of a mop wringer constructed in accordance with my invention;

Figure 2 is a side elevation thereof;

Figure 3 is an end elevation thereof;

Figure 4 is a section on the line 47 4: of Figure 2.

Figure 5 is a detailed sectional view through one of the standards showing a modification of the manner of supporting tee pedal.

Referring to these drawings, 10 designates a base upon which are mounted the opposed standards 11 and 12. One of these standards supports a transversely extending plate 13 longitudinally slotted at 14:. The "other standard supports upon it a pulley 15 and one end of a roller 16, the other end of which is supported by the plate 18. Also mounted upon the upper end of the standard 12 is a slightly curved arm 17 longitudinally slotted at 18. This arm extends approximately parallel to the plate 13. The roller 19 is slidingly supported at one end in the arm 17. The other end has a gudgeon 2O operatively supported within the slot 14. The gudgeon 20 both rocks ano slides within the slot i l and is held from coming out of this slot by a pin 21.

Connected to the extremity of the gudgeon is a coiled contractile spring 22 whose remote end is connected to one extremity of the plate 13. The gudgeon 23 on the opposite end of the roller 19 is connected by the cord, chain or cable 24 to a vertically sliding pedal 25 having guides 26 engaging the upright 12, the cord passing over the pulley 15 being then connected to the pedal. The uprights 11 and 12 are braced from the base 10 by means of braces 27.

Disposed in the length of the chain or cable 24 and preferably disposed between the end of the cable 2% and the pedal 25 is a coiled contractile spring 28. I do not wish to be limited to any particular means for connecting this spring between the cable 24 and the pedal or in the length of the cable 24 as the spring may be disposed in place in many different ways but by the use of this spring a resilient or yielding pressure is secured upon both ends of the roller 19 when the pedal 25 is depressed. Thus by the use of the coiled spring28, the pedal 25 may be forced all the way down to the floor and be held there by the pressure of the foot and yet through the yielding tension exerted by the coiled springs 22 and 28, the rollers16 and 19may yield orbe forced apart by the thickness of the mop while the mop is being pulled through or between said rollers. This secures a perfect wringing of the mop without the operator having to regulate the pressure on the pedal 25 with his foot and this avoids the possibility of the operator of said device becoming overbaL anced and falling.

Both of thesprings 22 and 28 will be of the properstrength and will serve the same purpose while the mop is being wrung. While I preferably show the coiled spring 28, I do not wish to be limited thereto, however.

In the actual use ofthis device, the coiled spring 22 acting on the gudgeon 20 acts to swing the roller 19 away from the roller 16 so t 121i) they have an angular relation to each other as shown in Figure 1. When, however, the pedal is depressed, the rollers are drawn into parallel relation and towards each other. Assuming that the mop is partially drawn through the rollers when they are compressed, then it follows, of course, that the coiled spring 22 will urge the end of the roller 19 adjacent the spring tcwardthe mop and the opposite end of the roller will, of course, be urged, toward the mop by the pressure applied on the pedal.

After the wrin ing of the mop is completed he coiled spring 22 will act to pull the rollers apart. These coiled springs also act as ten sion members allowing the rollers to spread apart slightly when the mop is being squeezed and this is especially true when the mop is thick. The coiled springs have a tendency to hold the rollers tight enough together to th0roughly squeeze the water out of the mop.

Other wringing devices known to me of the same general character as mine usually have the wringer and'the water bucket combined. This is hard to clean and further necessitates that the housewife buy both the wringer and the bucket.

As shown in Figure 5, the pedal 25 may be slidingly mounted upon the standard 12 by means of rivets 29 passing loosely through the vertical slot 3 in the pedal. It will be understood that the article may be made with either the guides 26 or the guides such as shown in Figure 5.

In my construction, the wringer and bucket are separate which permits the use of buckets that the housewifehas on hand and further when the water is to be emptied, there is a no necessity of carrying the wringing device with the bucket nor is there any necessity of unclamping a wringing device from a bucket as is the'case with ordinary wringing devices.

There are relatively few parts in my device to get out of order and the device may be readily made and sold at a relatively low cost.

It is pointed out that in the present construction the wringer rolls are disposed in horizontal planes and that the movable roll operates in a horizontal plane so as to permit the mop to be lifted up above the wringer and then move down through or between the wringer rollers.

My device is very simple and has been found thoroughly effective in actual use. Obviously minor changes might be made without departing from the spirit of the invention as defined in the appended claims.

1. A mop wringer of the character described, including a supporting frame adapted to receive a bucket, bracing means for said frame, a fixed roller mounted upon said frame and being thereby'supported across the top of t. e bucket in a horizontal p0sition, arms extending outward from the frame in the same direction and away from the fixed roller, one of said arms being short and the other long, both of said arms being slotted, a movable roller having gudgeons eX- tending through the slots of said arms, a con- "ractile spring engaging the gudgeon extendthrough the short arm and urging this nt of the roller toward the fixed roller, and pedal mounted upon the supporting frame and operatively engaged with the other end.

of the movable roller remote from said spring.

2. A mop wringer of the character described, comprisin a base, a pair of vertically extending standards on the opposite sides of tie base, one of the standards hav ing a relatively short slotted arm and the other of said standards having a relatively long slotted arm, a fixed roller supported upon 1 d standards, a pulley mounted upon.

the standard having the long arm, a pedal slidably mount d upon the standard, a movable roller having gudgeons extending through the slots to said arms, the roller being mounted for rocking movement into or out of parallelism with the first named roller, ,a contractile spring engaging the gudgeon at that end of the movable roller engaged with said short arm, the spring acting to thereby rock the movable roller into divergent relation to the fixed roller, the gudgeon at the opposite end of the fixed roller extending through said slot, and a flexible connection between the pedal and said last named gudgeon and passing over said pulley.

In testimony whereof I hereunto affiX my signature.
